Pyridoxal 5′-Phosphate Pyridoxine, also known as vitamin B6, is necessary for the transformation and utilization of amino acids for many functions in the body, including energy production and neurotransmitter synthesis.* Vitamin B6 is also involved in the production of hemoglobin, intrinsic factor, and is a vital component in the formation of the myelin sheath that surrounds nerve cells.* But in order for pyridoxine to be used by the body it must first be converted to pyridoxal 5′-phosphate (P5P), a process that takes place in the liver.* Individuals with compromised liver function have difficulty making this conversion and consequently may be at risk of a vitamin B6 deficiency.* Supplementing with Thorne’s Pyridoxal 5′-Phosphate ensures you receive the most bioactive form of vitamin B6.* Ingredients One Capsule Contains: Vitamin B6 (as Pyridoxal 5′-Phosphate) 33.8 mg.
